With a tv-based computer system, using reflective markers attached to 4 subjects' right index fingers, peak velocities were measured of fast hand movements in both directions between a midline target and left and right sided targets. Peak velocity increased with distance. Movements between the midline and the right sided target (ipsilateral) were faster than those between the midline and left sided target (contralateral). Adduction movements were faster than abduction movements. Retesting two subjects showed a high degree of variability in the peak velocities attained, but the same pattern of faster ipsilateral and adducting movements was found.
使用基于电视的计算机系统,通过将反光标记附着在4名受试者的右手食指上,测量了在中线目标与左右两侧目标之间双向快速手部运动的峰值速度。峰值速度随距离增加。中线与右侧目标(同侧)之间的运动比中线与左侧目标(对侧)之间的运动更快。内收运动比外展运动更快。对两名受试者进行重新测试发现,所达到的峰值速度存在高度变异性,但仍发现了同侧和内收运动更快的相同模式。
